Speakers; Subwoofer - Arcam AV860 Manuel

A subwoofer will greatly improve the bass performance of your
system. This is useful for reproducing special cinema effects,
especially where a dedicated LFE (Low Frequency Effects)

speakers

channel is available, as with many discs encoded with Dolby or
More than one subwoofer unit may be required for larger
installations, particularly in rooms of a timber frame
The AV860/AVR850/AVR550/AVR390 allows you
to connect up to seven speakers and up to two active
subwoofers in the main system. The output channels
correspond to speakers installed in the front left, centre,
front right, surround left, surround right, surround back
left, surround back right, height 1 right, height 1 left
and an active subwoofer. In addition, up to four height
speakers can be attached using an additional power
amplifier, see page E-16 for more information.
With the addition of correctly installed and configured
height channels, Dolby Atmos for the home brings the
ultimate cinema sound experience to your home theatre
to create powerful, moving audio that flows around you.
The configuration and placement of your speakers is
very important. All speakers, with the exception of the
subwoofer(s), should be arranged around your normal
viewing/listening position. The subwoofer should be
placed in a position which gives an even frequency
response in all listening positions. Incorrect placement
leads to bass boom in some areas. Often the only way
to find a good position for your subwoofer(s) is by
experimentation. A good place to start experimenting
is close to a wall but at least 1m away from any corners.
You can also consult your subwoofer handbook for
placement suggestions.

Centre
The centre speaker allows for a more realistic
reproduction of dialogue. The centre speaker
construction.
should have a similar tonal balance to the front
left and right speakers and be positioned at a
similar height.
Surround left and right
The surround left and right speakers reproduce
the ambient sound and effects present in a
multichannel home cinema system and should be
installed slightly higher than the listener's ears.
E-15
Surround back left and right
The surround back left and right speakers
are used to add extra depth and better
sound localisation and should be installed
approximately one metre higher than the
listener's ears. Place the two surround
back speakers such that there is an arc of
approximately 150 degrees between each
surround back speaker and the centre speaker.
The surround back speakers should face the front
of the room as shown in the diagram to provide
the largest 'sweet spot' .
Height speakers
With the AV860/AVR850/AVR550/AVR390
up to four height speakers can be attached and
can be either mounted in the ceiling or 'Dolby
enabled' elevation speakers - see page E-34 for
more information.
Front left and right
Position your front left and right speakers to
achieve a good stereo image for normal musical
reproduction as well as for the multichannel
modes. If they are placed too close together there
will be a lack of spaciousness; if they are placed
too far apart a stereo image will appear to have a
large 'hole' in the middle and will be presented in
two halves.
